To all f whom 'it may concern:

Be 1t known that I,- FLoYD FITz-Tnlzn BiNGimM, a citizen of the UnitedStates,

residing at San Jose, in the county of Santa Clara and State ofCalifornia, have invent-v ved certain new and useful Improvements 1nMotor-Cycles; and l do hereby declare the following to be a full, clear,andexact description of the invention, such as will enable othersskilled in the artvto which it appertains to make and use the same.

My invention relates to what are known as motor cycles, or that classofbicycles in which power can be' applied manually, as through pedals, ormechanically, 4as from a motor, gasolene or otherwise. I

My inventionembodies in a novel manner all the elements of the drivingmechanism within the traction wheel and includes in combination with amot-or a friction driving roller of vnovel construction and function andhaving a brake mechanism and arranged so that in its driving functionthe wheel will be free of the weight of the motor, its support, and itsoperating connections with the resulting advantage of a free startingand driving power, and in the claims appended hereto lI will set. outthe parts and combinations and arrangement thereof wherein my inventionresides. Aln the organization of my new motor cycle I prefer tov usewhat is known as the diamond frame with pedals at the lower-corner orangle, and provide the rear end of said frame with asubstantiallycircular yoke lifetweengand constituting a rigid part of the rear armsof the frame, and around which the traction wheel is rotated by adrivingroller mounted within said wheel and adapted to be actuated byveither the motor or the pedals.y An embodiment of the'invention isshown in the accompanying drawings in which Figure 1 ls'a side elevationof a motor.

Referring more articularly to the drawings, 1 indicates -t e frame.which is preferably ofl substantially the usual diamond shape, atthe'forward endofl which the front wheel 2 vis mounted by means of thefork 3.

Handles 4 are' vsecuredy to the head of the fork for steering themachine' and the grips l '5, or lhand holds are rotatably mounted on theends thereof for actuating the mechanism that controls the motive powerand will be hereinafter. morev fully ex lained. A'motor sup ort,preferably in the orm of an annular pate or yoke 6, Fig. 25, is ri idlysecured between therear ends 27 o the 'frame by means of fastening boltswhich pass through vthe frame ends and eccentric disks 67 and intoscrew-threaded socketed proiections 7 upon diametrically opposite,points of the yoke. A motor 8 of any suitable construction is mountedon the yoke and transmits its power throu h the sprocket and chain 9 tothe driving rol er, the weight of the motor being thereby placed so lowthat it assists in balancing the machine.

Secured to the bottom of the crank case 10, and to the lower side farmsof the wheel supported frame, and also between the two braces`1l, aretwo annular plates or rings 12,

one at each side of t-he rear wheel, and

around and upon roller bearings in said rings the rear wheel is causedto revolve. Arranged at suitable distances around the rings are bolts13, Figs, 1', 2 and 15, five being shown in the drawings, upon which aremounted the hollow axles 14, Fig. 2, for supporting the flanged rollers15. These rollers engage frictionally with and support. thesupplementary rim 16 of the wheel. The rollers preferably run on ballbearings and their cupflanges vform guards for preventproduced by ges20.` 'The inner flange is pre erably provided with side anges 21, Fig.15, between which 1 is placed a strip or band 22 of compressed orlndurated fiber.` The band andflange 17 are rovided with registeringperforations 23, Fig. 15, through which spurs or projections .24,011 thedriving roller band 47 extend for connecting the web flange andsaid wearband for propelling the machine said wear band serving also to reducethe noise the vroller bearings and the driving-roller., 4

The driving-roller Fig. 15 is mounted on an axle or bolt 26 and asleeve-25 on each end of the bolt the inner end of each sleeve beingexternally screw-threaded and cou-v pled together by an interiorscrew-'threaded union bushing 29q the outer ends of said 'sleevesterminating eachV in a ball-bearing and a Shouldered'end which abutsagainstV clips 28-28 to which the sleeves are tened by a nut on'theouter end of the bolt. Upon the ball-bearing 'end of each sleeve 25 islooselyftted a shorter sleeve 31 its' outer end vformed with aball-bearing overhanging the ball-bearing of the sleeve 25 formlngfthecounterpart thereof the sleeve end having an external screw thread; andn upon these two shorter sleeves 31, is screwed a union sleeve 36. Uponthe outer end of each union sleeve 36, is screwed la cone 38-39 thepoints of the cones being .toward each other and overhanging the unionsleeve 36. A friction drum 37 is loosely fitted upon the middlenonthreaded part of the union sleeve 36 and has a vdoubleconical formcorresponding with the overhanging inner ends of the cones, and upon theouter surfaces, of the cones is fitted a shell 40, the

inner side. of which has a double conical form corresponding with andconforming to the outer surfaces of the cones. The outer endof each conehas a. shell form which is screw threaded both internally and externallyand at the base or outer end of the cone the shell end is provided withballbearing cups L12m/43, the cup 42 being vot' L sha e in cross sectionand the cup 43, bcin of3 T shape in cross section and set upon the ballsand the cup 42 screwed upon the outer screw surface of. the outer end ofthe cone, thereby holding the bearing balls 1n 'their seats. A washer 45is placed between the shouldered cup end of sleeve 31v and the .outerside of cup 42 and against this washer the sprocket wheel 32 is screwedupon the liiang'e 17 of the wheel, whereby the roller is locked to the.wheel, while the perforated band is locked to the vshell 40, by 'meansof shoulders 48 on the edge'of said band adapted4 to engagecorrespondingly shouldered projections' 49 on the periphery of theshell, whereby the roller is positively driven by means of thesprocket-wheel 32 which is driven by the-motor'through the'chain 9,which also extends to and connects with the treadle sprocket 90.

The sprocket-wheel 34 is screwed upon the shouldered end of `the othersleeve 31 corresponding to the sprocket wheel 32 and is actuated by achain 35 connecting said sleeve with the treadlesprocket 90, so thatwhile the roller is rotated by the motor through the chain 9, it maybealso rotated by the joint action of the sprocket wheels 32 and 34. .Theroller driving-axle orbolt is mounted at its ends upon the side arms 27of the frame by means of a pair of clips 28. To complete the connectionof the roller members so that it may be driven as an eii tirety, thefriction drum 37 is formed of two segmental sections and at the splithas diametric recesses 41 Fig. 17 into which projections 41, on theinterior of the shell 40, engage and thereby lock the shell memberstogether; while the function of the conesl servesto give an expandingpressure to the impinging 'members 37-40 the vinner member 37 upon theunion sleeve 3G, and the outer member 40 upon the inner wall of theperforated band and thereby the desired y pressure or friction betweenthe shell inembers is maintained. It is this construction j which, whilecausing the positive rotation of the traction wheel by the toothedlengagement of the band 47 with the web oft-he wheel, allows thesprocket driven cones to be started by a slipping movement in contact.witliand between the shell members 37 and 40, to counteract the effectof the sudden starting acting on the driving roller upon the wheel. Itis this construction which provides the slightly yielding frictionalfunction of the cone members of lthe roller which will prevent damage tothe wheel mounting` parts from the sudden starting of the motor. In thisoperation it will be understood that the positive drivin engagement withand function of the ro ler with the traction wheel, willibe uniinpaired4and the efficiency of the driving function of the roller will bemaintained with the desired speed.

The friction drum 37, Fig. 17 surrounds the central portion of sleeve 36and is held in engagement therewith by two adjustable friction cones 38and 39 better shown in Fig.

19. The drum is `preferably formed from segmental sections and the endsare beveled orinclined so as to be engaged by the inner surfaces of thecones. An interiorly beveledfriction shell 40. Figs. 18A and 19,surrounds the two cones and the drum 37 and engages positively with thelatter by means of internal projections 41, which fit in correspendingrecesses 41 Fig. 17, in the periphery of t-he` central portion of thefriction drum.- Between the outer ends of the friction cones 38, 39 andthe outer ends of the cone shells 31 are formed ball bearing cones andcups 42 and 43, respectively `the outer edge of each of the cups beingprovided with a flange 44, which engages with the rings 12, and lassistsin holding the roller in p0- sition.

After the cones have been adjusted between the friction drum 37 and theshell 40 to secure the desired pressure or friction between the surfacesof the cones and the sur-A faces of the d ruin and shell, the cones areheld in position by the feathered washers 45 Figs. 15 and 16, which titbetween the sprocket wheels and the cones 42, the

sprocket wheels beinor secured against displacement by the lol notedreferring to Fig. 15, that the sparking-lever 53 is fitted to swing'loosely upon the ball-bearing cup43 between the ringframe 12 and theshoulder 44 of the ball bearing cup 43 and is thereby kept in verticalposition. It will also be noted that the band-spurs 24 arepreferablyformed with heads so` as to -tit the -perforations in the band and arethereby rendered removable so that in case of wear or breakage they maybe r-nuts 46. Itwill be 4 iio replaced; and that the band v47 ismaintained by its-shoulders 48 in lockingengagement with the ,shell 40,by a ring-nut 50, so as to be positively rotated by the shell.

The operation of the frictionally yielding mechanism by which damage tothe roller parts and their connections is avoided is as follows: Thefixed members of the roller are the bolt or shaft 26`; the -ball bearingsleeves 25, 25, which are connected by the bushing 29 and fastened tothe clips 2S-28, and the ball-bearing cups 43.43 which are secured tothe ring-frames12 which are fixed parts of the main frame.

The rotating elements and their functions are as follows: The frictioncone 38 is screwed externally on the bushing 3B at one end and insertedinto the shell 40 which has a wide' double beveled surface; next isinserted the segmental double beveled friction bushing 37 which is keyedat tour points to the shell next. is screwed on the friction cone 39externally at' the other end of the bushing 36. 38-39 simultaneouslywill cause them to wedge or crowd into the sloping surfaces 'ot shell 40and upon bushing 37 which, will in tui-ii, bind sutliciently for acertain amount of slippage upon bushing 36 forming thereby a frictionalconnection through the ball- 31-31 and bushing 36, and finally to thefriction cones 38 and 39, causing them. to rotate in a jerky manner andgradually impart full frictional hold to the sloping sur- :faces of theshell Li0 as the motor gains headway at about half speed. Y

The ball bearing cups 42 and double cups 43, are necessary to give freerotative play to accommodate the jerky power transmissions. When theniotor cycle attains full speed and the motor is running smoothly, allrotary parts in the driving-roller will revolve in unison becausecomplete frictional hold is attained automatically.

A brake is provided for the drivingroller and consists of two pairs ofsemi-cir'- cular brake members 51-51 Figs. 22-23-24 and 31, whichencircle the' plain surfaces 51a of each end ot the roller-shell 40 asseen in Fig. 15 and are operated by a wrist-lever 52 which is looselymounted on the upper tiXed tie-bar and iits between one end of saidroller and one ot the hired rings 12 which support the wheel. The ringsare rigidly connected by a pair of nuttedtiebars 59;'59 and on one ofthese tie-bars the upper end otono ot the levers 52 is loosely mounted,the lower end ot' said brake being pivoted by an ear 5S to the lever bya wristpin 5G fixed thereon. The otherA brake is loosely mounted itslower end to the other tic-bar 59, the upper end of this brake beingpivotally mounted by an ear 58 on a wrist-pin 56 fixed on the lever. Thefixed tie-bars are therefore, diagonally on opposite sides of the.roller and the wrist-pin of each strap is opposite one o't the tie-barsand each is movable with the lever. By this construction it is evidentthat when the lever 52 is moved forward by its connected rod 61, bothbrakes will. be simultaneously closed and set upon the roller-shell 40to check and stop the speed of the machine as' in Fig. 23.

Now, screwing up the cones brake.

ln this movement ot the lever the `1appel' wrist-pin of one ofthe brakeswill be moved toward the lined tie-bar and the lower end ot' the otherbrake will be moved in the opposite direction toward the other fixedtiebar. The opposite movement ot the lever causes the brakes to beopened releasing the An identical pair ot brakes 51-51 is litted uponthe opposite end of the roller as in Figs. 21k and 29, and each brake isconnected in an identicalvmanner to the same tie-bars and pivotallyconnected to wristpiiis 56-56 on a lever 53, which is loosely mounted onthe other lower fixed tie-bar 59 between the other end of thedriving-roller and the other fixed ring 12 and has wristpins 56-opposite lengthwise of the roller, those on the brake-lever 52. Toetlect the simultaneous operation of lthese separate and distinctbrake-devices on the opposite ends of the driving-roller l provide thefollowing means. The levers 52 and 53 are connected together by theirrespective wrist -pins .5G-56 which are connected by a sleeve 57 Fig.31, the pins being within the sleeve and braced together', the upper andthe lower pairs of wrist-pins being separately connected by such sleeve57.a The ends of these sleeves .areshouldered and lit against the innerwalls of the levers Fig. 2st and rigidly connect the wrist-pins andcause them to torni rigid connections for the levers so that themovement of the lever 52 will simultaneously and to the same extent,inove thelever 53 and thus cause the two pairs of brakes to he appliedand released, the levers for this purpose being swung upon the roller,and the brakes each upon its respective fixed tie-bar. To render uniformthe grip of the brakes upon the driving-roller. their ears 5S, have eacha slot whereby the. brakes are adapted tor self adjustment upon theirrespective tie-bars and wrist-pins` while the tie-bars and theirfastening nuts A60, serve to bind the ears of the brake and theshouldered sleeves together and thereb)v give firmness to the connectedlevers and render .them movable together with a firm brake function uponthe roller.

iii-addition to the brake function of the lever 53, l utilize it as themeans tor eon- Ytrolling the sparking mechanism 5t in a well knownn'ianneithrongh a link'eonfor this purpose being directly and brakes tobe closed upon the roller and at the same time and by the same levermove- 1nent.cause the lever 53 to be forced downward throwing thesparking-device out 0f,

.act-ion and stopping the motor. This construction provides controllingmeans for the motor and its sparking mechanism with cooperating meansfor controlling the brake by the steering-handle of a motor drivenvehicle, whereby the relation of these coacting elements gives theadvantage of simultaneous operation of the motor and of the brakecontrolling mechanism and at the same time gives the rider control` inthe guiding of the cycle, one of the handle-bars ositively connected tothe motor and top the brake controlling device's, so that the partialrotation of one ofthe handle-bars causes thesimultaneous action of themotor, its sparking-device and the brake devices in controlling themovement lo the cycle; while the partial rotation of the otherhandle-bar gives the rider control of the oil The arrangement andconnections of the `rods 6-1' and 107, provide a very effective controlof the machine, and for this purpose the brake-operating lever 52depends from one end of the driving-roller so as to connect withitsoperating rod 61 below the treadle-shaft from which it is supported by adepending swing larm 95 at one sideof the frame; while the lever -53stands horizontally rearward from the other end of the driving-roller inconvenient positionto be'connected bythe depending link 55, with thesparking-device, so that the rider, by means of one of the handle-gripconnections withthe rod 61 hasy control /over the brake and Koverl thesparkingdevice. The other handle-grip by its connections with the rod107, at the other side of the frame, gives the' rider control over thefuel-supply.

The importance of providing the drivingroller with the brakes is that itcauses the power to control' the speed of the machine to be `applieddirect to the inner web' of the traction Wheel and thereby efect the'quick stopping of the machine.

The sparking apparatus vwhich may be located at 54 within the wheel, maybe of .any well known character but I prefer to use one thatis adaptedto' be energized b v y magneto mechanism 02, Figs. 1 and 21, that .1slmounted at the side of the motor upon extensions 63 on the braces11,'which brace extensions are joinedtogether by a curvedh brace 64.

Power can be transmitted to the driving roller by the'rider through thepedal mechanism which consists ot the usual crank, preferably formed oftwo similar crank ar1ns68, Figs. 3, 6 and 7, which have their inner endstapered wedge-shape and are held in al clutch sleever69, Figs. 3 and 4,by a bolt T0,-tapped. into the crank-arms, the sleeve being preferablydivided longitudinally and held together by two screw collars 71 and thecone bearings 72 at its ends.

Mounted upon the central portion of the .clutch sleeve 69 is a clutchplate 7 3 which is adapted to be rotatably connected with the sleeve bypawl and ratchet mechanism, pref-` erably balls 74, Fig. 14, which lfitin inclined recesses formed in the sleeve and the plate respectively. 4

Rigidly secured to the outer edge of the clutch-plate 7 3, are twoannular frames 76, Figs. 3, l1 and 12, the dianietrically opposite edgeparts of which are bent outward AVor away from each other as. shown at77, and perforated for bolts 78, F igs.v 3 and 10, upon which are seatedball-bearing cones 79. Rotatably mounted on each pair of conesl byball-bearings is a duplex sleeve-like pinion 80, Figs. 8 and 10, whichis adapted to engage with an. internally1 duplev geared annular rim 81on one side and with two central pinions 82, Figs. 3, 9 and'lO, on theother, the clutch-plate being recessed as at for the pinions 80. Theannular cogged rim 81 is rigidly secured within a surrounding seat orshell 84, of the frame 1 by two exteriorly Screw threaded caps 85, andthe central pinious S2 are rotatably mounted between the huh of theclutchrplate 73 and he caps 85 by means of the ordinaryball-bearing cups86. A sprocketcap S7, Fig. 3, is rigidly secured upon the outer end ofthe hub of each of the pinions 82 and is supported by ball-bearingsbetween the cones 72 andcups 8S that -are secured to the flanges 89 onthe inner edges" of the cap screw S5. Sprocket wheels 90 and 91 aresecured to the peripheries of the caps 87 bynut locks 93 and 94. Byarranging the wheel rim and inions in this manner and making the plnionsonly half the dianieter of the pinion 82 the sprocket wheels will becaused to rotate three times for every rotation of the pedal shaft.thereby giving three times the speed that could be secured by direct.

connection of the s1nocket-wheels with the lao upon and held in place onone of saidfftangeg by one ot said nuts and the/ro/d 61K extends fromtll am! 95 i0 titel/ever or Wrist-plate downwardly and inwardlyextending lips or 52 and therebymntrols the brake mechanisni. A*Thebrake-lever 52, which, by means `hereiiiafter stated, is connected toand operates the lever 53. is adapted to be oscillated byone of thehandle grips 5 through a flexible shaft 96, in the handle bar, a head`lever 97, a rod 98, a bell-crank lever 99 and a rod 100. The inner endof the flexible shaft is angular and fits in a corresponding hole in thelever 97 so that when the grip is'rotated the outer end of the leverwill be movedup or down Yand motion transmitted through 'the rods to setor release t-he brake, as the' case'm'ay be.- Tliecrank-lever 99 ismounted on a stud 101 which projects fromior is rieidly4 secured to theside of the head or fork post of the frame. c are preferably providedfor connecting the rod 98 with the levers 97 and 99 respectively.

' The other handle grip 5 is connected inl a similar manner with a headlever 103 that i controls the fuel supply 104, Figsfl and 30,

, fork connection, the other arm-of each bellvby a rod which controlsthe brake and the through. rod .105,'bell-crank lever 106, and

rod 107, the lever v106 vbeing mounted in the saniemaiiner'as lever99and the rod 105 lbeing' connected at itseiids by means of swivel headsthe sameas rod 98. The' rod 107 connects. with and extends from thebell-crank lever 106,toand connects with the lever 124 by which thefuelsupply 104, Fig. 29, is controlled. The handle-bars at their meetingends 108' are Xed by screwb'olts 109 to the steering post and thecentral portionl of the bars is cut out to form ahollow centra-l..lspace open at the front side of the post andthrou'gli which hollow theupper end of the steering-post passesk and through which open lspa-cethe levers 97 and 103 project in positions to be connected to thebell-crank levers 99 and 106 vniounted'on the post'. The advantage of,this constructionis the compact, convenient and durable arrangementupon the steering 'post of thev mechanism for controlling thefuel-supply, thesparking-device, and the brakes and in whichone of thehandle'bars forms the meaiis of controlling the fuel-supply and theother handle-bar the means for controlling the sparking-device' and 4thebrake mechanism. For this purpose 'each handle-bar has a flexible shaftthe end of each terminating in the handle-space which is provided toallow tlie'arnis 97 and 103 to be fixed to each end of the flexibleshaft to stand out side by side, and from the end -of each a rod dependsby the side of the post and is connected t-o one 'end ,of an` arm of abell-"crank-lever mounted onl each side of the post near its crank leverbeing connected-one by a rod which controls the fuel supply and theother sparking devices.-so that all Vthe connec- -tions are Amade togirev a direct thrusting force' from each. tleifible shaft and therebyprevent lost motion of the operating connections; and to` render thehandle arms. andv the bell-crank levers free from binding or crampingthey are connected to the depending rods by swivel-heads or links sothat. each flexible shaft will have a quickl and certain action upontheir connections.

Seated within the lower part ofthe frame 1 immediately in front of theseat post and adjacent to the pedal mechanism, is av tank -110 for oi]which communicates with the motor mechanism through a pipev111 andreservoir 112. A tank 113 for fuel, as gaso'-- I lene, is mounted withinthe frame 1 between the top of the tank 110 and the top bar of the frameand communicates with the car bureter 114 through a valved pipe 115.

The lubricating oil is preferablyv fed under air pressure which issupplied through an openingllG in the tank 110 byan ordinary hand pump.,(not shown), aiidthe tank 113 is filled through an opening 117.

-The lseat is mounted at the rear ends of two springs 119 that areloca-ted upon'op, posite sides of the-frame andv are'pivotally connectedat their forward ends to the-ends of two other springs. 120 by links121-.- A Blocks 122 separate'the intermediate por tions. of the' springsand the rear ends of the' lower springs 120 are pivotally connected withthe seat post as shown at 123.`

At their front ends the upper pair ofsprings are connected each to astud on each side of the'franie head and tothese studs the uppereiids-ofthe links 1,21 are also-connect.-`

ed,. so that the upper and lowerfsprings of each pair .are connected andsupported 01,1 each side of the top frame-bar and their rear'en'ds tothe opposite. sides ofthe frame. The links 121 arein pairs on each sideof the frame and connect and serve, as spreaders for the front ends ofthe springs, so thatthe weight of the rider is carried by the rear halfof theupper pair .of springs 119, the middle block and the studconnections at the front ends ofthe upper springs and the studconnections of the rear ends of the lower pair of springs.- j

By constructing a motor cycle as `above described the greatest weight isplaced directly overntlie point of contact of the driving wheel with theground whereby lati-iig the hand grips without letting go of thehandle-bars. All sudden jars from thc ldriving mechanism are taken up infriction .without being transmitted to the supporting wheels. 'The seatis so yieldingly but firmly 'supported that the rider not incon- 'ring.power from the motor to the drivingroller and from the treadley tothedrivingroller. i For instance, should the slack of the vch'ains becomeso great that the extreme rear position of the bolt 26 inthe slot 30 asin Figs. l to 28 may be necessary to take up the entire slack, the bolts26, are then loosened and the eccentrics are adjusted to move thedriving-roller arrangement 26 to' the extreme forward ends of the slots,to remove one or two links in each of the chains. To move thedriving-roller lforward is to move the'wheel with its ring-frames 12and. fthe motor as an entirety in the same direction by properlyactuating the eccentrics as shown in Fig.v33. The center of the yokearms7 is the center of the ring-frames 12 and also of the traction-wheel. Iftherefore, the centerof the yoke and the centers of the eccentricsbe inline vertically` the driving roller arrangement 26 Awill assume aposition in themiddle of the length of the slot 30 as in 34. Referringto Fig. 1

' Y it will be seen that the brace arms 11 which connect the main'fra-lne arms with the ringframes 12 serve as tie-bars of fixed length.between the centers .of the yoke-arms and the center of the Wheelsupporting .roller rings at the frontjendsfof the frame arms,

and'tha-t'fany adjustment of the driving`" roller arrangement 26 and.the eccentrics 67 either forwardly orrearwardly will not af feet thecontact of the. rollersl of the ring frames with the web of the tractionwheel.V Therefore, the mechanical adjustment of the above members forthe purpose'of adjusting the chains 9 andl 35 is effected by theconstruction described, but such adjustment of the driving roller cannotbe land is not intendedv to be made independent of the eccen'trics. Thebearings 'for the eccentrics are formed in the socketed arms rigidlyvfastened to the ends' of the frame as in Fig. 35; .while in Figs.v25,35 and the eccentrics 67 are seen mounted in pairs one uponIhayokearms 7 andthe other upon the bolt and are secured to each side ofan annular fillet 67, of the arms.

It is important that the driving-roller be` firmly and durably'mountedand'for this purpose 'each end. is fixed tightly. Within openings in therings 12-and upon the periphery of the ball-bearing cups 43, which arefixed members of the roller, the shoulders 14, of said ball-bearingcups, abutting cn the outside of the rings which are cnlarged at theopenings within which the roller yis fixed, as in Figs. 1 and 28. Thedriving roller therefore, is not only firmly fixed in the wheelsupporting frame of which the rings are members, but isalso firmly fixedby its bolt or axle upon the arms of the main frame and the nuts on theends of the bolts, so that when the driving roller is set with its spursin engagement with the wheel-flange, it is fixed in such adside of thewheel on a horizontal' radial line causes the' pulling force of .thesprocket chain to maintain the driving-roller firmly against thej flangeof the wheel and renders certainv the automatic engagement of the spurspf the driving-roller as it rotates, with the perforation's in thelflange of the wheel. W'hile the jmachine maybe propelled by thetreadlefmechanism, it [will be understood that the importance of thetrea'dley is to start the machine as well as the motor and thus serve,to reduce the jerky action` in starting the motor.

I have stated that the motor transmits its" power through the sprocketand chain 9, and referring to Fig. 1 it will -be seen that this chain isthe connection 'between the driving roller and the motor, and in makingsuch connection the chain passes around the pedal sprocket wheel Fig. 3and also aroundthe motor sprocket wheel and overA and engagingthedriving roller. sprocket- .wheei s2, Fig. 24.

erating connections and which the 'lever 53, on the driving roller, isseen connected by the link 55 with the sparking device, and thebrake-lever 52, is seen connected by the rod 61,' with the arm 95, whichhas` the actionof a bell-crank and formsthe intermediate lconnection forthe rods Glimd 100, between the brake-lever 52, and tl e gripcontrol ofthe handle connections.

y It is important to note that the mounting 0f the driving roller at theslide of the traction-wheel in aline approximately coincident with thehorizontal radius thereof, gives the advantage of operating thedrivv1ng-roller with an easy starting and driving operation inpropelling the machine, and for this purpose the shaft of the drivingroller is mounted in the -rings and in the frame arms and causes therebythe steady support and `running of the traction-wheel, because theposition of the driving-ruiter is such as to relieve it of the weight ofthe operating elements within the wheel. It. is also important to'not'ethat all the driving elements areY supported, within the'tiact-ionwheelupon a horizontal central-ring which connects and braces thev rear armsot" the frame and that the wheel is rotated around this ring uponfriction-rolls mounted upon and betweenva pair of vertical rings oneoncach side of the wheel and supported between and' by the 4arms vof theframe thus forming a bracing structure for the wheel` and itsl drivingelements, and whereby the driving-roller may be operated by a tieadleoperated chain so that the wheel may be tion "drum, a bandl around thedrum pro-- vvided with means for engaging with said wheel, and frictionmeans connected with.
